I want to ask some questions about IPExpert lab 21. Some of them
are not technical question but the way to understand what is the task
request
us to do.

1: In the switching part, it request us to change the spanning tree
age timer to 20. But I don't see any config relate to spanning-tree timer
in
the final config. Is that "age timer" means max age in the result of "show
spanning-tree vlan xx"?
